Improved Analysis of Polyfluorinated Alkyl Substances in Environmental Samples Using Optimized ASTM Method 7968/7979

This article evaluates ASTM D7979-16 for the “direct” analysis of 30 PFCs and 19 mass-labeled surrogates. Instead of using solid-phase extraction, the PFCs were solubilized in a methanol–water mix and filtered if necessary, and the sample was injected into a LC–MS/MS system.
